Tv fix Our tv when turned off it won't come back on but the power button blinks, i think five times repeatedly. we can finally get it turned back on by plugging and unplugging repeatedly but are now afraid to turn it off. Help please!

I thinks you need use a new power board instead of the old power board ,you can have a look https://www.abctay.com ,you may find what you need.

5 times LED blinks in Panasonic PT-47WX42 shows problem with convergence out chips failure as this tv has two big black ICs STK392-110 as convergence output, replace them to fix tv problem.

the green light blinking is normal if set has been unplugged--when set is plugged back it should blink for about 70 seconds and then go out--then you can try to turn it on---it is the DM unit inside the set booting up.

If the light just blinks and never stops you have likely bad caps in the DM unit---there are kits available for that.

The other possible reason is that so called reset switch may be bad--fairly easy way to find that out and it is more common than you would think, let me know if you have questions.

When it shuts off and the green power light goes off, press both the menu and input buttons on the front of the set (not the remote) and hold both for about five seconds and release.

Power light will blink a two digit error code like 2 blinks and then 3 blinks and repeat it several times.

What is the error code?

IF model number posted is correct and green power light comes on for a few seconds and then goes off:
On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.

Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code is found and I will tell you what it means.

You will need to press the menu button and the input buttons on the TV both in together for five secoinds then count the two digit blink code from the power indicator. the blink sequence will repeat several times. let me know the sequence of the blinks.

do the self check this set has, when power light goes off, ON THE FRONT OF THE SET PRESS AND HOLD BOTH THE MENU AND INPUT (DEVICE) BUTTONS FOR AT LEAST FIVE SECONDS AND RELEASE BOTH.

Watch the power light, it will blink a two digit error code=====most common is two blinks, two blinks a pause and it will repeat the code several times.

This is to narrow down where the problem is.

Let me know what error code you find and I will tell you what it means.

SD TECH

next time it shuts down and power light goes out--do the self check.

On front of set press and hold BOTH MENU AND INPUT BUTTONS FOR AT LEAST FIVE SECONDS AND RELEASE BOTH BUTTONS.

Power light (if an error is detected) will blink a two digit code.

Most common is 2 blinks, pause and 2 blinks---set if there is a error code will repeat it at least 5 times.

If you detect a error code, let me know and I will tell you what it means.

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

Sounds like the remote is not programed correctly or the input sources have been changed.

Call the cable company and complain that it worked before they came and shoud work afterwards.
